class TEveViewer: public TEveWindowFrame


 Eve representation of TGLViewer.

 The gl-viewer is owned by this class and is deleted in destructor.

 The frame is not deleted, it is expected that the gl-viewer implementation
 will delete that. TGLSAViewer and TGEmbeddedViewer both do so.
 This could be an optional argument to SetGLViewer. A frame could be
 passed as well.

Function documentation

TEveViewer(const char* n = "TEveViewer", const char* t = "")
 Constructor.
 The base-class TEveWindowFrame is constructed without a frame so
 a default composite-frame is instantiated and stored in fGUIFrame.
 Cleanup is set to no-cleanup as viewers need to be zapped with some
 more care.
~TEveViewer()
 Destructor.
void InitInternal()
 Initialize static data-members according to running conditions.
void PreUndock()
 Virtual function called before a window is undocked.
 On mac we have to force recreation of gl-context.
void PostDock()
 Virtual function called after a window is docked.
 On mac we have to force recreation of gl-context.
const TGPicture* GetListTreeIcon(Bool_t open = kFALSE)
 Return TEveViewer icon.
void SetGLViewer(TGLViewer* viewer, TGFrame* frame)
 Set TGLViewer that is represented by this object.
 The old gl-viewer is deleted.
TGLSAViewer* SpawnGLViewer(TGedEditor* ged = 0, Bool_t stereo = kFALSE)
 Spawn new GLViewer and adopt it.
TGLEmbeddedViewer* SpawnGLEmbeddedViewer(TGedEditor* ged = 0, Int_t border = 0)
 Spawn new GLViewer and adopt it.
void Redraw(Bool_t resetCameras = kFALSE)
 Redraw viewer immediately.
void SwitchStereo()
 Switch stereo mode.
 This only works TGLSAViewers and, of course, with stereo support
 provided by the OpenGL driver.
void AddScene(TEveScene* scene)
 Add 'scene' to the list of scenes.
void RemoveElementLocal(TEveElement* el)
 Remove element 'el' from the list of children and also remove
 appropriate GLScene from GLViewer's list of scenes.
 Virtual from TEveElement.
void RemoveElementsLocal()
 Remove all children, forwarded to GLViewer.
 Virtual from TEveElement.
TObject* GetEditorObject(const TEveException& eh = "TEveViewer::GetEditorObject ") const
 Object to be edited when this is selected, returns the TGLViewer.
 Virtual from TEveElement.
Bool_t HandleElementPaste(TEveElement* el)
 Receive a pasted object. TEveViewer only accepts objects of
 class TEveScene.
 Virtual from TEveElement.
TEveViewer(const TEveViewer& )
TEveViewer& operator=(const TEveViewer& )
TGLViewer* GetGLViewer() const
{ return fGLViewer; }
